Application filed December 26, 1905. Serial No. 293,366.

To all whom it 'may concern.' l c Be it known that we, ZioN E. Fivnnsii and CHARLIE BxLEoNARD, citizens of the United States, residing at Rawles Springs, in the `county of Perry and State of Mississippi,

have invented a new and useful lNood-Dis- I tilling Apparatus, of which the following is a specification.

This invention relates to means for ex- `tracting the various well known' products,

such as creosote, turpentine, and the like from wood.

The object is to provide an apparatus that is comparatively simple in structure, is entirely e'fiicient for the purposes intended, and is very convenient to operate.

rPhe preferred form of structure is illustrated in the accompanying drawings, wherein. Y

Figure 1 is a side elevation of the apparatus. Fig. 2 is `a verticallongitudinal sectional view therethrough. Fig. 3 is a front elevation of the chute and a portion of the conveyer, parts-thereof being broken awayA and shown in section. fFig. 4 is a froiit. elevation of the lower portion of the retort chamber and the conveyer, portions of the latterbcing broken away. Fig. 5 is adetail sectional view through the lower door.

Similar reference numerals designate corresponding parts in all the iigures of the drawings. l

In the embodiment illustrated, a support ing ,structure is employed comprising'a frame 6, on which is supported a retort chamber 7,

' comprising a cylindrical body, located at an inclination and havingheads-Q, constituting the end walls of the chamber. Saddle brackets 10, securedto the cylinder and resting` on the supporting frame, serve to inain-4 tain the chamber iii proper osition. The

heads 9 are disposed in angu ar relation, so

that the lower one will assume a more nearly vertical position and the upper one will be disposed in more nearly a horizontal plane. The upper head is provided with an. inlet l opening or doorway 11,fand the lower head has a corresponding outlet openingr or door way 12. These openings or doorways are arranged to be closed by swinging doors 13,

hinged attheir upper edges, as shown'at 14,

to the heads, and carrying ears l5 at their lower ends, which ears are arranged to 'bev engaged by stud bolts 16, carried by the heads, said stud bolts' receiving r holding nuts 1,7, that engage over tli'e ears. Suitablelead Specification of Letters Patent.

or .other gaskets 18 are employed to 'obtain' tight joints about the doorways' when the doors are in closed position. i f

.For the purpose of heating the chamber and the contents thereof, a steam 'pipe 19, leading from any suitable source of sup ly, has connection with a heater pipe/exten ing. longitudinally within the lower portion of the retort chamber, said supply pipe having a controlling valve 20. The heater ipe comprises sections 21 and 22, connected) -by a coupling 23. perforate, while the lower section 22 is provided with suitable perforations, constituting outlets for the steam. tion 22, furthermore, preferably projects through the lower head ofthe chamber and is closed by a-cap 24. -A distillate conduct`- `ingr/pipe 25 is connected to the upper end of the chamber and has a controlling valve 26. This pipe 25 is connected to a condenser coil 27, arranged within a tank 28, which coil proiects from thetank and is provided with a discharge nozzle 29,5 having a dip 30. A gas ,ventiBl is connected to the nozzle in advance of the dip 30, and said nozzledelivers to a suitable receptacle, as 32, which recep- The upper section 2]. is im- This lower sectacle is provided with a siphon 33, connect-v A ed to the lower portion thereof and having a vent 34.

Means are provided for supplying .the

chamber with material. Inthe present einbodiment, a chute body 35 is mounted on a suitable supporting frame 36 and has a bottom 37, that incliiies downwardly towardthe The vcrticalwall-SS of the chute body that is diss' posedadjacent to theupper end of the re' tort chamber has a discharge lopening 39, located in line with thedoorway 11. A gate l10, hinged, as shown at 41, to the vertical wall 38, controls the discharge and is adapted to be maintained in closed position by turn buttons 112.` vA oonveye'r leads from' the mill vor other apparatus at which the material is prepared. Said l'conveyer comprises a trough 43, 'leading over the' top of vthe .chute 'and having an opening 41,'in its'bottom, coin- An endless chain 45 operates longitudinally in the troughand is' provided with spaced cross slats 46, that; are disposed'traiisversely ofthe trough. A similar refuse conveyei; co. operates with the lower discharge openingor IOO `doorway-l2 of the 'retortv chamber to remove the refuse lfrom the vicinity thereof AThis conveyer consists of a trough 47, in which operates an endless chain 4S', having crossed slats Ait), disposed transversely ol the trough. The latter con Teyer leads to any. suitable point of discharge.

The material is preferably, in the form of sawdust, chips, or similar small pieces, being brought to the apparatus by the conveyer chain and the crossed slats and deposited in the chute. Wien it is desired to charge the retort chamber, the up )er door is opened and the material is allower. to pass from the chute into the chamber. When sufficient material is collected therein the upper door is closed, and steam is admitted. to the chamber through the pipe 1.9, and the sections 2l and 22. The pressure ot the steam within the chamber be ascertained by means ot suitable-gage 5 0, connected to the upper4 I end. of the chamber.

The products, in the form oi vapor, will pass oli through the pipe 25 and will be condensed in the'coils 37, estaping through the `nozzles 29 in the receptacle .32. By having the upper portion 'of i." e steam supply pipe imperforate, and the lower portion perforate, it will be apparent 'that-the steam escaping from said ipe must necessarily pass through practical y the entire body of the material within the retort chamber', before it escapes through the pipe 25, and thus the full body oi' material will be proferly treated. The water, collecting at th ttom, may oe drawn off through the thus leaving .tue desiredv distill'use, u is only necessary to open the lower door i125, whereupon the same will be discharged. into the lower conveyor and be carried thereby away from the vicinity of the perratas.A lt will be apparent that this .it is simple and convenient to opermoreov'r-n', it will perform the functions ired with eiticiency and expedition.

lfrom the vforegoing it is thought that thel construction, operation, and many advantages of the herein described invention will be apparent to those skilled in the art, without further description, and it will be understood that various changes in the size, shape,. proportion., and minor details of construction may bi. sorted to without departingr from the spirit or'sacrilicing any ol the advantages of the invention.

Having thus described our invention what we claim as new and desire to secure by Letters Patent, is;

l. ln a still of thev character described, the combination with a retort chamber, of means for feeding material thereto, said means i1- cluding a chute located above the chamber and a conveyer delivering to the chute, said conveyer comprising a trough having in- 'io remove the re-` clined sides located over said chute and having an open bottom that communicates with the chute, and a conveyor. i'light moving in the trough over the o )en bottom but exceeding the width of said bottom.

2. In a still ot the character described, the combination with a retort chamber set at an inclination and having a discharge opening in its lower end, of means for feeding material to the upper Aend of the chamber, and means for conveying the refuse from the lower end of the chamber, said lattermeans comprising a trough located exteriorly of the chamber and receiving the material directly from the discharge opening, and an endless flightoperating in the trough and including scraper slats disposed transversely of and operating through the trough.
